I'm planning to upgrade from my old Dell Dimension E521 to a homebuild system, meant for middle-range gaming. I've recently (in my stupidity) bought a Geforce GTS250, only to find out that it just won't fit in. As a result, I've decided to see if I can build myself a relatively cheap PC, preferably while re-using things such as some of the RAM, Processor and the hard drive.
So, to get to my actual question:
I'm starting out with my Geforce GTS250, a Dynex 500W power supply and (ideally) re-using my 250GB hard drive and 2GB RAM.
Since I'm completely and utterly new to the PC-building, I was wondering if you guys can recommend me a decent case, processor (if I can't re-use my AMD Athlon 64 X2 Dual Core 4400+) and, most importantly I guess, motherboard. I'm pretty sure I'm currently running an on-board soundcard, and since I'm no audio-enthusiast I have no problem doing the same for my new system.
Additional info: I don't really require any accessories like mouse, keyboard, speakers, monitors, etc. I'm running Windows Vista, and currently have no plans to upgrade to 7.
Since I'm not looking to buy a whole new setup but rather recycle as many parts as possible, the ones mentioned above, motherboard, case, processor (if needed) are everything I'm trying to get to new. As such, I'd prefer I would have to spend no more than $400.
I'm planning to re-use the memory, power supply, disc drives and hard drive, as well as the processor (if possible). Also, I already have that Geforce GTS250 that I'm planning to use.
I was thinking of the fan for the CPU. I'm pretty sure there's one installed on my current rig, too, and if I was to reuse it on the new build, I was wondering if there could be any compatibility problems with the new motherboard.
From what I have seen so far, it doesn't seem like Dell is providing very adaptable hardware...
EDIT: Yeah, it's DDR2 memory... so I guess I'll have to buy new memory, too. Bummer.
